OIL-STONE.

SPECIFICATION forming part of Letters Patent No. 262,113, dated August 1, 1882.

Application led February 11, 1882. (No model.)

To all whom it may concern:

Be it known that we, JAMES B. PEIRCE and BURRELL A. Piemon, of Browne Hill, in the county of TWythe and State ot' Virginia, have invented certain new and useful Improvements in Oil-Stones, of which the following is afull, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure lis a plan view of our improved oilstone with the cover removed. Fig.2isa seetional elevation taken on the line w x, Fig. l, showing the cover in place. Fig. 3 is a similar view taken on theline 1/ y, Fig. 1; and Fig. 4 is a perspective view of a screw-driver or other tool to be held in the block.

This invention consists principally in providing the block in which the stone is set with an oil-reservoir, the same being provided with means for forcing` the oil from the reservoir upon the stone as needed.

The invention also consists in the details of construction andthe combinations and arrangement of parts, all as hereinafter more fully described.

In the drawings, Arepresents the block; B, the oil-reservoir, and G the stone, which is set in the block A. The block is formed with the chamber A', of suitable size, under the stone, to receive the reservoir B, and the reservoir is held in this chamber by means of the yoke or strap d. The reservoir is provided with the filling-tube f and with the discharge-tube g, which, when in place, pass up through the openings e and i, lea-ding from the chamber A to the upper surface ofthe block, and the upper end of the discharge-tube is bent so as to stand over the stone in position for directing the oil as it is forced from the reservoir over and upon the surface of the stone. The oil is forced from the reservoir by means of the piston-head or follower D, which is secured upon the inner end of the rod E, which rod protrudes from the front end of the block, where it is provided with the knob h, which furnishes a convenient hold for drawing the piston-head or follower forward in the reservoir for forcing the oil through the tube g upon the stone. The rod E is provided, inside the reservoir, with the coiled spring j, which forces the pistonhead to the rear end ot' the reservoir as soon as the rod is released, and retains it always in that position. The forward end of the rese-rvoir is closed with the screw-plug H, which is formed with the stufngbox lc in its center, through which the rod E passes, and forms a tight bearing for the rod. The outer end of the filling-tubo is closed by the screw-plugf', which can be removed from the upper surface ofthe block for filling the reservoir, as will be seen from the drawings.

In order that the rod E will always be held in convenient position for forcing the oil upon the stone, wel provide the forward end of the block with the bow J, which is perforated for the passage of the rod E, as clearly shown.

Thus constructed, it will be seen that oil for use upon the stone will always be handy and easily applied to the stone, and that the res ervoir can be easily filled, making the device complete and convenient.

The cover K is formed with an enlarged chamber, L, so as to fit over the stone and the lling and discharge tubes, as clearly shown in Figs. 2 and 3.

In the block, near one edge, is formed the slot or incision n, in which the screw-driver or other tool, N, is placed and conveniently held for use.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. rIhe combination, with a block, of an oilstouo and reservoir arranged one above the other in cavities of said block, the said reser-` Voir being connected by a pipe with a space over the stone, and provided with means for forcing the oil through said pipe, for the purpose specied.

2. The block A,'formed with the chamber A', in combination with the reservoir B, provided with the piston-head D, rod E, dischargetube g, and filling-tube j', substantially as described.

3. The reservoir B, provided with the discharge-tube g and lling-tube f, in combination with the piston-head D, rod E, spring j, rod E, sprngj and the cover K, the block be- :md stung-hox 7.1, substantially as and for the ing provided with the bow J, substantially as 1o purposes described. set forth.
